The paper provides a critical analysis of Uwe Meixner’s modal argument in favour of psychophysical dualism. It delivers, first, a formal reconstruction of the proof which was originally presented by Meixner in 2004, second, a detailed scrutiny of some premises of the argument in question, and third, a careful assessment of the whole reasoning. My analysis aims at justifying the belief that although the version of the modal argument invented by Meixner is formally valid and represents a significant progress when compared with the original version, it is still based on two disputable premises which make the whole reasoning difficult to regard, in a completely collision-free way, as a materially sound one.
